Peter Crouch headed the Potters ahead but Robin van Persie's 35th goal of the season was enough to snatch a point for the Gunners.

The French defender was happy to come away from the Britannia Stadium with a point after a difficult game against Tony Pulis' side.

"They are a very physical team. The play a lot with free-kicks and they attack with the ball," Sagna told Sky Sports.

"But we managed to come back. It was very important because it's never easy to get some points here but today it might be a very important point."

The draw moved Arsenal four points clear of fourth-placed Newcastle, who have a game in hand, but suffered a 4-0 defeat at Wigan on Saturday, and Sagna is keen to wrap up automatic qualification to the Champions League.

"Some teams are behind us but we know we have our destiny in our hands," he added.

"We've worked a lot to come back to third place and we want to stay and qualify straight away."
